NLAD-LINGLEUM MACHINE.

Application lcd November To all @IJ/0m t may concern.'

Be it known that l, JOHN TAMBERLIN, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain improvements in lnlaid- Linoleum Machines, of which the following' is a speciication.

rllhis invention is designed primarily to improve the manufacture of inlaid linoleum by holding the shapes comprising the design upon the backing in lined relation as the same move from the pin band to and through the press, and for preventing the shapes from sticking to the press head when forced thereby against the backing upon the heated press bed to eifect the adhesion of the shapes to the backing.

The invention is characterized by the combination of means for intermittently moving a backing with shapes placed t-hereon, intermittently pressing the shapes upon successive sections of the backing during the periods when the same are at rest, and automatically holding the shapes in place upon the backing as well as protecting such shapes from contact with the press as the fabric passes from the mechanism by which they are placed through the press.

The invention is disclosed in the mechanism set out in the following description and the accompanying drawing in illustration thereof.

The drawing illustrates a broken side elevation of an inlaid linoleum machine embodying my improvements.

The invention, as represented in the drawing, is combined with an inlaid machine having a frame 1 provided with a liournalled drum 2 over which passes a pin band 3 adapted for carrying a burlap backing sheet -t having linoleum shapes 5 arranged thereon.

A press frame 6 is provided wit-h a hollow steam heated bed 7 over which the backing with the shapes arranged thereon is drawn by the friction roller 8, the. backing passlng from the pin band to the press bed over the intermediate table section 9.

An endless linen band 10 passes over the end rollers 11 and 12 which are supported by the respective bearings 13 and 14e carried by the frame adjacent to and parallel with the pin band drum and the card roller re 2, 1320, Serial No. 421,277.

spectively, and over the top roller 15, which is carried by the bearings 16 on the guides 17' supported by the frame 6.

The band 10 engages the top surfaces oi the shapes 5 and holds them in proper' relation upon the backing t as the same is carried over the press bed i', the band being revolved with the traveling linoleum y frictional engagement therewith.

A press head or block 18, having the bearing 19 adapted for movement in the guides 17, is reciprocated within the top and bottom limits of the band 10 and intermittently acts therein to press the registeringl section thereof against the underlying shapes 5 of composition and forces them into adhering engagement with the backing et.

rlhe head 18 is reciprocated by the action upon the trunnions 20 carried by the bean' ings 19, of the connecting rods 21 which are operated by the pins 22 of the revolving cranks 23. The connecting rods are fixed in adjustable relation to the trunnions through the segments 20 connected in oscillatory relation with the latter and provided with the eccentric slots 20 through which and the connecting rods are passed bolts 21.

The crank pin 22 is connected by a rod 24 with the pin 25 of 'a crank 26 which is fixed on a journalled shaft 27, the revolution of the latter reciprocating the head 18 through the intermediate mechanism described.

An eccentric 28 is fixed on the shaft 27 and revolves in a collar 29 which is connected by a rod 39 with an arm 31 adapted to rock on the drum shaft 2. A pawl 32 carried by the arm 31 engages a ratchet wheel 33 fixed to the drum 2, which is revolved thereby step by step to advance step by step the pin band 3 and the burlap l with the shapes 5 over the parts 9, 7 and 8 and under the parts 10 and 18.

rlhe crank 26 and the eccentric 28 'are so disposed that while the head 18 is in engagement with the band 10 in the operation of pressing the shapes on the backing, the pawl 32 is being retracted so that the pin band 3 is stationary, and when the head 18 is elevated the pawl 32 is acting positively to advance the pin band with the linoleuin thereon. Hence, the linoleum will be stationary during the engagement of the press head therewith or with the band thereon and will move forward beneath the band, which is carried therewith, while the press head is disengaged therefrom.

It will be understood, therefore, that in operation 'the backing sheet 1, with the linoleum shapes 5 arranged thereon, is carried by the pin band 3 and the friction roller 8,

over the table section 9 and the heated bedy i' and under the traveling band 10 and the reciprocating press head 18; that the revolving' eccentric 28 'acts through the parts 29, 30, 31 and 32, upon the ratchet wheel 33 and the drum 2 fixed thereto to effect the movement of the sheet l with the shapes 5 thereon, together with the band 10, intermittently over the bed 7, simultaneously with its action through the parts 27, 26, 25, 24, 23, 22, 21 and 2O in reciprocating the head 18 out of contract with the section of the band engaging the shapes 5; that 'as the eccentric acts througl'i the intermediate parts to retract the part 32, the parts 83, 2 and 3 will be stationary, as also the sheet e andthe shapes 5 thereon together with the part 10, and that while the sheet with the shapes thereon and the band in Contact therewith are 'at rest the eccentric forces the head against the apron.

The shapes, in adhesive condition and rendered more adhesive by the heated press, are thus squeezed between the backing fabric of relatively coarse texture and the band of relatively fine texture with the result that such shapes are pressed into the meshes of the backing fabric and spread to close up the joints between them.

Having described my invention, cl'aiin:

1. A linoleum machine comprising the combination of a pin band for moving a backing fabric with tesserte thereon, a press, means for moving said fabric and tessera@ through said press, means for divertings'aid pin hand from said fabric before entering said press, and an endless band holding the tesseraa on said fabric at the point of separation therefrom of said pin band.

A linoleum in'achine comprising the combination of a pin band for moving a backing fabric with tesserse thereon, a drum, by which said pin band is diverted from said fabric, a press spaced from said drum, means for moving said fabric and tesserae through said press, and an endless band extending over the surface of tesserae on said fabric between said drum and press, said band passing with said tesserae and fabric through s'aid press, whereby the rtesserae passing through said press are housed between said fabric and band.
